XR Voice-and-Pointing Control for Precise Digital Object Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing XR environments, such as those on the Meta Quest platform, lack the ability for users to easily place or manipulate digital objects using voice commands and pointing, limiting user interaction and customization.
Innovation Solution
A method and system that combines voice commands and pointing gestures, using a user's hand or virtual tools, to specify the location and attributes of digital objects within XR environments, leveraging artificial intelligence to generate and manipulate these objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users interact with digital objects in XR environments using traditional control methods, then device complexity is reduced, but ease of operation deteriorates due to limited interaction capabilities
Solution Approach 1:
The patent combines voice commands and pointing gestures into a unified interaction system. The voice command module processes natural language instructions while the pointing detection module captures spatial intent, and together they control digital objects in the XR environment. This merging of multiple interaction modalities improves ease of operation without significantly increasing perceived device complexity.
Solution Approach 2:
The interaction system is designed to handle multiple types of commands through a single unified interface. The same voice command and pointing combination can create new digital objects, move existing objects, delete objects, or modify object properties. This multi-functionality improves operational ease while avoiding the need for separate control mechanisms for each function.
2Adaptability or versatility
If XR environments provide more customization options for digital objects, then adaptability improves, but ease of manufacture deteriorates due to increased system complexity
Solution Approach 1:
The system automatically generates digital objects based on voice commands and pointing input without requiring manual configuration. When a user points to a location and issues a creation command, the system autonomously determines object properties, positions, and initial state. This self-service approach enables high adaptability while keeping the system relatively simple to implement.
Solution Approach 2:
The system enables customization of digital objects by allowing users to modify parameters such as position, size, color, and type through natural voice commands. The underlying system handles parameter validation and application automatically, providing versatile customization capabilities without requiring complex manual configuration interfaces or intricate system architecture.

AI summary
A user with an extended reality hardware device creates and changes appearance of a digital object in extended reality environments by using voice commands including adverbs in conjunction with pointing action of a hand at location point. A representation of the digital object is retrieved for display at the location point pointed to by the user.
